Figure 2. — Dive chronology of penguin SP1801: (a) entire foraging trip recorded, (b) enlarged timeslot demarcated as vertical dotted lines in (a), and (c) images from AVRs indexed to time. The number of birds (n birds) in flight and at the surface are shown: Cape cormorants (CC, grey), sooty shearwaters (SS, black) and African penguins (AP, blue). Prey captures by volant seabirds (inter catch, tern = swift tern) and by African penguins (AP catch for schooling and single fish) are superimposed on the dive profile. Images show CC (left panel) and SS (right panel) prey pursuits/catches: sooty shearwaters are located at terminal ends of bubble trails foraging at the periphery of the fish schools. Confirmation of species identification of volant seabirds confirmed from images in sequence not displayed.
